Help Please! This is my first Ford, a 99 Ranger 3.0 Flex Fuel,recently while driving home the T on one of my heater hoses where the smaller hose t's to the intake slit resulting in coolant loss and a blown head gasket on the passengers side,coolant was leaking into my no.2 cylinder,everything checked out so I replaced the gasket and eliminated the t in both heater hoses and plugged the two hoses coming from the top of the intake,all seemed well as it started and ran fine when suddenly misses and white smoke, I pulled the plugs and the side I replaced gasket on all were dry but now my no.6 cylinder had coolant leaking in and further checking showed water was also getting in my oil,can anyone help me ,was plugging the 2 manifold lines a mistake,I am also building immediate pressure in my radiator which is bubbling back through my overflow tank,what am I missing?

 

The heater hoses to the intake are just for pre-heating the air in the intake, many delete them, that doesn't cause any problem.

I assume from your post you only changed the passenger side head gasket, if so that was a mistake.
You need to replace both head gaskets after an overheating issue that caused a blown head gasket, both gaskets were crushed by the overheating.
If you did replace both then drivers side was just done wrong, it happens.

If engine hasn't been over heated again then you could just change drivers side head gasket now.
You do need to replace the head bolts each time they are removed, the TTY bolts will either break when reinstalled or break after a few heating and cooling cycles.

Overheating causes metal in the head and block to expand more than "normal" this crushes the softer metal rings in the head gaskets that seal the cylinders, pressure and heat in the cylinder will find a weak point and burn thru to the gasket material which can't hold back much pressure, and since each cylinder is surrounded by cooling passages the head gasket leak is first noticed as too much pressure in cooling system, i.e. full and bubbling overflow tank.
If allowed to continue the leak will usually push thru to an oil drain or passage, and you get "milkshake" oil in the pan.

The head metal gets the hottest so expands more than block, which is why you get cracked heads along with blown head gaskets.
So if you are repairing a blown head gasket you should also take both heads to machine shop and have then surfaced and pressure tested just to be sure there are no cracks
